Parade of Nations: Which Countries Are (and Aren't) in the Olympics? (Paris 2024)

This is an updated version of an article first published in 2012. To see previous versions, view all Olympics articles on PolGeoNow.

Map of all countries in the Olympics and their regional associations. By Evan Centanni, modeled after this map.

The 2024 Summer Olympics are officially opening this Friday, July 26. This year they're officially hosted by the city of Paris, France, though events will be held all around the country. This is the sixth time France has hosted the games (including the Winter Olympics). It's also Paris's third time to host the Olympics, though it took a break for 100 years. The only other city to host three times is London, in the UK.

Of course, it wouldn't be an Olympic opening ceremony without the Parade of Nations. But how many countries are there in the games, and is everyone included? Read on for PolGeoNow's updated guide to the roster of Olympic Nations...

How Many Countries Are There in the World in 2024?

This article, originally from 2011, has been revised and updated to July 2024. You can view older versions of the article in our archives. The main update from last year is the surrender of the self-proclaimed Artsakh Republic (Nagorno-Karabakh), whose territory is now controlled by Azerbaijan.

One of the most basic questions for map-lovers is "How many countries are there in the world?" But anyone who just gives you a simple number isn't telling the whole truth. It actually depends a lot on how you define a "country". Here are six of the most common answers, each correct in its own way:

Israel / Palestine Map: Who Controlled What Before the 2023 Hamas Invasion?

This article was originally published in July 2020, but has been revised and updated to October 2023. The design of the accompanying map has also been slightly revised, but there were no changes to territorial control between the previous edition and this one except for the reopening of the Gaza fishing zone.

This map shows the situation just before the current war began. For the war itself, check out our new map showing control at the height of the October 2023 Hamas invasion the next day.

Israel and Palestine Controlled Areas: Before the War

October 2023's surprise invasion of Israel by Palestinian fighters from the Gaza Strip has catapulted the area back to the top of world headlines, and the situation on the ground is now in flux. But what exactly was the situation just before this new chapter of the conflict started? This newly-revised version of PolGeoNow's Israel/Palestine explainer article answers all your questions about who's who and what the significance of each disputed zone is. 

The accompanying map has also been slightly revised and newly fact-checked to ensure that it shows the situation accurately as of October 6, 2023, the night before the Hamas-led invasion of Israel (the only change to control is that the Gaza Strip fishing zone was apparently open for most of this year, rather than closed as it was at the time of our 2021 update).

Note that this is a map of who actually controls what, not of who claims which areas. And it's definitely not supposed to imply that any particular party should or shouldn't control any particular area. As always, PolGeoNow takes no side in these disputes, and we have done our best to report only the facts.

What is the Eurozone?

Officially called the "euro area", the Eurozone is a nickname for the group of countries in Europe that share a single currency, called the euro, as their official money. The euro currency is managed by the European Union (EU), but many countries in the EU don't use the euro, and some countries outside the EU do use it. The European Central Bank, headquartered in Frankfurt, Germany, is in charge of regulating the currency and making euro coins and bills (bank notes).

Map of the Schengen Area, Europe's Border-free Travel Zone

Editor's Note: As of January 2023, the Schengen Area now includes Croatia. The map and article below will soon be updated to reflect this.

What is the "Schengen Area"? What's the difference between Schengen and the EU? And which countries does Schengen include? Read on for all the answers, explained in plain English!

Important note: Though borders within the Schengen Area are normally completely open, countries can sometimes bring back temporary (or even long-term) ID checks. You can check for recent maps of the situation by viewing all Schengen border control articles on PolGeoNow. This is especially true during the 2020 global coronavirus pandemic, when many countries have not only brought back border controls, but are also turning away foreign travelers.
